1, typical application WG series zero-power magnetic sensors can only be used for rotation detection. Moreover, a magnet must be installed on the rotating object to be measured. At present, most of the WG series zero-power magnetic sensors are used in civil heat meters and electronic water meters. In the electronic water meter, the wg type magnetic sensor adopts a symmetrical driving mode, and the rotating shaft end is equipped with a permanent magnet, and a pair of pulses are output in one revolution, and the amplitude is about 1v. In this design of the magnetic circuit, the magnetic flux should be passed through the center of the sensor in parallel, and the magnetic induction at the midpoint of the center should be controlled at about 6 mt. If used under high temperature conditions, there should be a certain margin in the design of magnetic induction, because the magnetic field strength of magnetic steel will decrease with the increase of temperature. Also need to pay attention to magnetic shielding to prevent interference from surrounding stray electromagnetic fields. The counting software can be programmed by the pre-processing circuit and supported by corresponding hardware. 2, special applications Based on the typical application of the sensor, in order to improve the accuracy of the measured flow, a multi-magnetic steel wheel rotation method was used. The magnets are evenly arranged on the disk edge. The n and s pole faces cross up and the sensor side is on the edge. The number of magnets in the disk is determined by the diameter of the disk. The fluid pushes the impeller, which is mounted on the lug wheel outlet shaft, thereby rotating and triggering the sensor operation. Since a plurality of magnets are installed in the disk, this causes the disk to rotate one revolution, and the sensor outputs a plurality of signals through the ratio of the size of the waist wheel to the flow, thereby obtaining more accurate flow data. The feature of the disc is that the magnetic steel is densely discharged on the edge of the disc, and the direction of magnetic lines of force of each magnet is disturbed, and a clearer alternating magnetic field of n and s cannot be formed. This makes normal magnetic sensors unable to work properly. The WG311 zero-power magnetic sensor overcomes this shortcoming by eliminating magnet magnetic field disturbances from the left and right sides of the target magnet steel and accurately catching the magnetic field of the working magnet steel to trigger it, enabling it to work properly in a chaotic magnetic field. This results in a significant increase in the accuracy of the measured flow rate. If the disk size is slightly modified and a variety of different amounts of magnet steel are installed, the accuracy will change accordingly, and the flow rate will be determined according to the flow rate of the flowmeter with different calibers. The sensor is designed to capture the special characteristics of a normal operating magnetic field in a disturbing magnetic field. The replacement use of the WG series zero-power magnetic sensor completely meets the actual requirements. Using a different processing method than the software processing, the peripheral wave processing is used to process the rectangular wave pulse directly into the single-chip computer processing, reduce software resources, realize signal sampling, and achieve signal compatibility with the flow totalizer. In summary, Through the selection of sensors, the special application of the WG series zero-dissipation magnetic sensor can completely replace the existing sensor in terms of structural processing or performance, and is completely ultra-low-speed detection in sensitivity performance. It is a magnetic sensor. Unmatched.
CNC milling is a machining process that uses computer-controlled and rotating multi-point cutting tools to incrementally remove material from a workpiece and produce a custom-designed part or product. The process is suitable for machining a variety of materials such as metal, plastic, wood, and producing a variety of custom designed parts and products. CNC Milling Machining has evolved over the years to produce precision milling parts that meet the stringent requirements of today's demanding industries. The applications for CNC Milled Parts are nearly endless and span many industries such as aerospace, automotive, robotics, medical and so on.
In the CNC machining industry, we generally divide it into CNC milling, CNC turning, and CNC turning and milling composite processing, and now also include a little CNC grinding. Three-axis CNC, four-axis CNC and five-axis CNC machining are commonly used in CNC milling. How many axes CNC are used for a workpiece mainly depends on the complexity of the workpiece and the accuracy requirements of the workpiece. We usually choose the machine tool and determine the processing technology according to the material, structure and precision requirements of the workpiece, and improve production efficiency and reduce production costs on the premise of ensuring that the requirements of the workpiece are met.
SCZY includes a batch of CNC milling machines imported from Switzerland and Japan, and some CNC milling machines produced in China. We can choose suitable machine tools for processing according to the specific requirements of customers' products, so as to achieve the best product state and the best economic state. Our highest accuracy can reach ±0.005mm (specifically, it is also determined according to the material of the workpiece and the complexity of the workpiece). Here are some of the products we've made:

Typical and Special Applications of WG Series Zero-Power Magnetic Sensors
WG series zero-power magnetic sensors have outstanding advantages of zero power consumption and zero response frequency. Because it is manufactured using the principle of material science, it also has zero power consumption of the reed switch and Hall sensor has good vibration resistance and stability. The advantages, compared with the non-magnetic sensor, it is zero power consumption, no contact, small size, flexible installation, low price, and consistent with the magnetic sensor performance. The WG series zero-power magnetic sensor is used as the transducer of the flowmeter to directly express the speed of the lumbar wheel with the number of electric pulses, which greatly reduces the pre-process of the system, and acts as a passive device sensor. At the same time, the total power consumption of the system is reduced.
